Summarizing the primary and the supportive stability data, it can be concluded: The NME drug substance BIWG 98 SE is stable. It should be stored in a tight container.

5 BIWG 98 SE drug substance Page 5 of Proposed Re-test period and Container closure system information A preliminary re-test period of 24 months is derived from the resulting data. The stability testing will be continued up to 60 months, with the intention of extending the re-test period up to 60 months, if the data adequately support that conclusion. After 60 months the samples are analysed for immediate use. Example: After release re-test period: 60 months After 5 years analysis before immediate use Preliminary Re-test period Container closure system Climatic zone Re-test period Polyethylene bag in stainless steel container II 24 months Storage instructions: According to the results no storage instructions are required, even if the shelf-life will be extended up to 60 months. Nevertheless storage instructions may be necessary due to the national requirements. Countries EU Japan Storage instructions none none USA Store at 25 C, excursion permitted to C

7 BIWG 98 SE drug substance Page 7 of Introduction In this report the primary stability testing is described with the 3 registration batches of the NCE drug substance BIWG 98 SE. The investigations were performed according to the ICH Guideline "Stability Testing of New Drug Substances and Drug Products".

9 BIWG 98 SE drug substance Page 9 of Container Closure System A tight container is necessary according to the stress investigations with the drug substance. Therefore the samples were packed in 500 ml glass flasks with twist-off closure lined with polyethylene foil type Lupolene 3020 D. The same polyethylene foil is used in the stainless steel containers of the chemical production. Therefore a possible interaction can be investigated. The tight stainless steel container was simulated by the glass flask with the twist-off closure. 3.3 Test attributes In stability testing of BIWG 98 SE the attributes were investigated which are potentially susceptible to change during the course of storage and which are likely to influence quality, safety and/or efficacy. The following test attributes have been selected according to the results of the stress investigations with the drug substance: Appearance, odour, colour of solution, clarity of solution, melting behaviour, water content, degradation of BIWG 98 SE, assay of BIWG 98 SE, Assessment of container closure system.

10 BIWG 98 SE drug substance Page 10 of Analytical procedures The analytical procedures were stability indicating and completely validated according to the ICH Guidelines on validation. Specificity was demonstrated by separating the drug substance from 3 degradation products caused by stress investigation. Intermediate precision: Initial assay: Reporting threshold: RSD 0.65 %, single analysis was possible since RSD 0.65 % < 1 % 3-fold 0.05 % according to the ICH Guideline "Impurities in New Drug Substances", each impurity > 0.05 % (reporting threshold) can be quantitated. The test attributes, the analytical procedures and the release specifications are summarized in the: "Stability Testing Specifications BIWG 98 SE drug substance No. TSS 900-A-01/02". The validation procedures and the corresponding data are summarized in the: "Validation Report BIWG 98 SE drug substance No. VRS 900-A-01/V01". The analytical procedures were developed for the stability testing of BIWG 98 SE drug substance. The same analytical procedures were used for the investigation of the registration batches.

28 BIWG 98 SE drug substance Page 28 of Evaluation The three registration batches packed in polyethylene bags in 500 ml glass flasks with twist-off closure were investigated. The samples had been stored up to 18 respectively 12 months at 25 C/60 % r.h. and up to 6 months at 40 C/75 % r.h.. The analytical procedures were stability indicating and completely validated Organoleptical properties: During the storage no change in appearance or odour took place Physico-chemical properties: During the storage at both conditions no change in colour of solution, clarity of solution, melting behaviour and loss on drying occurred Chemical properties: During the storage no fall in assay took place. No degradation > 0.05 % was detected. Two known impurities did not change. Since no decomposition or fall in assay took place, the statistical evaluation was deleted. This is underlined by the graphical presentation of the data of assay of BIWG 98 SE. These data scatter slightly Container closure system properties: No interaction was found with the polyethylene foil Photostability: The Photostability was investigated applying the Suntest CPS (Atlas Corp.). After 22 hours (Confirmatory Testing) no change in any test criteria took place. According to the results BIWG 98 SE is not light sensitive.

29 BIWG 98 SE drug substance Page 29 of 30 5 Conclusion The NCE BIWG 98 SE is a stable drug substance. The Accelerated and Long-Term Stability test results with the three registration batches confirmed fully the data of the Stress-testing with the drug substance. No change took place in the organoleptical, physico-chemical, chemical and container closure system properties. Due to the hygroscopicity a slight increase in loss on drying was indicated. The drug substance is not sensitive to light according to the Photostability investigation. The tested polyethylene foil can be used for storage and shipment. The drug substance must be stored in tight containers. Special precautions for handling during production are not required. A preliminary re-test period of 24 months can be derived from the primary and supportive data. the stability testing will be continued up to 60 months with the expectation to extend the re-test period up to 60 months. It means all stability data are within release specifications.
